(Undated) -- More countries are joining the United States in a boycott of the 2022 Beijing Winter Olympics. Australia, Canada and the United Kingdom said Wednesday they are all taking part in the diplomatic boycott. Activists have been calling for a boycott for months over human rights abuses by the Chinese government. Beijing was accused by the US and other nations of imprisoning more than a million Muslim-majority Uyghurs in detention centers, where they say they were tortured and abused.
